Valve nkimwe mubikoresho byingirakamaro mubikorwa byinganda, kuva guhitamo kugeza kubikoresha bishobora guhura nibibazo byinshi, hano Xiaobian yakusanyije ibibazo bisanzwe, reba niba bishobora kugufasha?
1 、 Ni ibihe bintu bitatu by'ingenzi bigomba kwitabwaho muguhitamo icyerekezo?
(1) Ibisohoka bya actuator bigomba kuba birenze umutwaro wa valve, kandi bigomba guhuzwa neza.
(2) Mugihe ugenzura ibipimo bisanzwe, birakenewe gusuzuma niba itandukaniro ryumuvuduko wemewe ryerekanwe na valve ryujuje ibisabwa. Iyo itandukaniro ryumuvuduko ari rinini, imbaraga zitaringanijwe kumurongo wa valve zigomba kubarwa.
(3) Birakenewe gusuzuma niba umuvuduko wo gusubiza wa actuator wujuje ibisabwa mubikorwa, cyane cyane amashanyarazi.
2 、 Ugereranije na pneumatic actuator, ni ibihe bintu biranga nuburyo bwo gusohora amashanyarazi?
Inkomoko yamashanyarazi nimbaraga zamashanyarazi, yoroshye kandi yoroshye, hamwe nimbaraga nini, torque no gukomera. Ariko imiterere iragoye kandi kwizerwa ni bibi. Birahenze kuruta pneumatike mubito kandi bito. Bikunze gukoreshwa mubihe bidafite isoko ya gaze cyangwa biturika biturika kandi bitagira umuriro.
Imashanyarazi ikoresha uburyo butatu bwo gusohora: gukubita inguni, kugororoka kugororotse no kuzunguruka byinshi.
3 、 Ni ukubera iki itandukaniro ryumuvuduko ukabije wa valve stroke ari nini?
Itandukaniro rinini ryo guca itandukaniro rya angle stroke ya valve ni ukubera imbaraga zivamo zakozwe nuburyo buciriritse kumurongo wa valve cyangwa plaque ya plaque ifite itara rito cyane kuri shitingi izunguruka, bityo irashobora kwihanganira itandukaniro rinini ryumuvuduko. Ikinyugunyugu na kinyugunyugu ni byo bikunze kugaragara cyane.
4 、 Nihe mibande ikenera guhitamo icyerekezo? Nigute ushobora guhitamo?
Kuri kashe imwe yo kugenzura kashe, nkicyicaro kimwe, icyuma cyumuvuduko mwinshi hamwe na kashe imwe yikimenyetso idafite umwobo uringaniye, icyerekezo gitemba kigomba guhitamo.
Gufungura no gutembera gutemba bifite inyungu zabo nibibi. Imiyoboro ifunguye ya valve ikora neza, ariko imikorere yayo yo kwisukura no gukora kashe ni mibi, kandi ubuzima bwumurimo ni bugufi; Imiyoboro ifunze valve ifite ubuzima burebure bwa serivisi, imikorere myiza yo kwisukura no gukora kashe, ariko ituze rirakennye iyo diameter yumuti itari munsi ya diameter.
Intebe imwe yintebe, icyuma gito gitemba hamwe na kashe ya kashe imwe isanzwe ikomeza gutemba, kandi gutemba birashobora gutoranywa mugihe gukubitwa gukabije cyangwa hari ibisabwa byo kwisukura. Imyanya ibiri yihuta gufungura igenga valve ni iyimyitozo yatoranijwe ifunze ubwoko.
5 valve Usibye icyicaro kimwe cyicaro kimwe, icyicaro cyimyanya ibiri na valve yintoki, ni izihe zindi valve zifite imikorere yo kugenzura?
Indangantego ya Diaphragm, ikinyugunyugu, O-ubwoko bwumupira wumupira (cyane cyane waciwe), ubwoko bwa V bwumupira wumupira (igipimo kinini cyo kugenzura no gukata) hamwe na eccentric rotary valve byose ni valve ifite umurimo wo kugenzura.
6 、 Kuki guhitamo ari ngombwa kuruta kubara
Ugereranije no kubara no guhitamo, guhitamo nibyingenzi cyane kandi bigoye. Kuberako kubara ari uburyo bworoshye bwo kubara, ntibiterwa nukuri kuri formula ubwayo, ahubwo biterwa nukuri kubintu byatanzwe.
Ubwoko bwo guhitamo burimo ibintu byinshi. Uburangare buke buzaganisha ku guhitamo ubwoko budakwiye, butaganisha gusa ku gutakaza abakozi, umutungo wibikoresho nubutunzi bwimari, ariko kandi biganisha kubibazo bimwe na bimwe byo gukoresha, nko kwizerwa, ubuzima bwa serivisi hamwe nubuziranenge bwibikorwa.
7 、 Kuberiki bidashobora gukoreshwa inshuro ebyiri zifunga kashe yo gufunga?
Ibyiza byimyanya ibiri yimyanya nimbaraga nimbaraga zingana, zemerera itandukaniro rinini ryumuvuduko, kandi imbogamizi zidasanzwe ni uko ibice bibiri bifunga kashe bidashobora guhura neza icyarimwe, bikavamo kumeneka kwinshi.
Niba ikoreshwa muburyo bwa gihanga kandi ku gahato mu guca ibintu, ingaruka biragaragara ko atari nziza. Nubwo hari byinshi byahinduwe kuri yo (nka kashe ya kabiri yikimenyetso), ntabwo byifuzwa.
8 、 Kuki icyicaro cyimyanya ibiri cyoroshye kunyeganyega mugihe gikorana no gufungura gake?
Kuri corps imwe, iyo igikoresho kigenda gifungura, valve ifite ituze ryiza; Iyo imiyoboro ifunze ifunze, ituze rya valve iba ikennye. Intebe yimyanya ibiri ifite ibice bibiri bya valve, intoki yo hepfo ya valve iri mumwanya ufunze, naho hejuru ya valve yo hejuru iri mumwanya ufunguye.
Muri ubu buryo, mugihe ukora mugukingura ntoya, gutembera gufunga byoroshye biroroshye gutera kunyeganyega kwa valve, niyo mpanvu ituma intebe yintebe ebyiri idashobora gukoreshwa mugukingura gato.
9 、 Ni ibihe bintu biranga kugororoka binyuze mu cyicaro kimwe cyo kugenzura intebe? Bikoreshwa he?
（1) Gusohora gake, kubera ko hariho akantu kamwe gusa, byoroshye kwemeza kashe. Gusohora bisanzwe ni 0.01% kV, irashobora gukoreshwa nka valve ifunga mugushushanya.
. Umuyoboro △ P wa DN 100 ni 120 kPa gusa.
(3) Ubushobozi bwo kuzenguruka ni buto. KV ya DN 100 ni 120. Bikunze gukoreshwa mugihe cyo gutemba guto no gutandukanya umuvuduko muto.
10 、 Ni ibihe bintu biranga igororotse binyuze mu myanya ibiri yo kugenzura intebe? Bikoreshwa he?
（1) Itandukaniro ryumuvuduko wemewe ni rinini, kuko rishobora kurwanya imbaraga nyinshi zitaringanijwe. Umuyoboro △ P wa DN 100 ni 280 kPa.
(2) Ubushobozi bunini bwo kuzenguruka. KV ya DN 100 ni 160.
(3) Kumeneka ni binini kubera ko ibice bibiri bya valve bidashobora gufungwa icyarimwe. Gusohora bisanzwe ni 0.1% kV, ni inshuro 10 za valve imwe. Ugororotse unyuze mu myanya ibiri yo kugenzura ikoreshwa cyane cyane itandukaniro ryumuvuduko mwinshi, ibisabwa kumeneka ntabwo ari ibihe bikomeye.
11 、 Ni ukubera iki imikorere irwanya guhagarika imikorere igororotse ya valve ikennye kandi iy'inguni yo kugenzura inguni nziza?
Intanga ya valve yiburyo bwa valve igororotse ni vertical trottling, mugihe urwego rutemba rwinjira kandi rutambitse. Umuyoboro utemba mu cyuho cya valve ugomba guhindukirira hejuru, bigatuma inzira itembera ya valve igorana cyane (nkimiterere ya "s" ihindagurika). Muri ubu buryo, hari uturere twinshi twapfuye, dutanga umwanya wimvura igereranije. Mugihe kirekire, bizatera guhagarika.
Icyerekezo cyo gutambutsa inguni ya stroke ni icyerekezo gitambitse. Ikigereranyo gitemba kandi gisohoka mu buryo butambitse, byoroshye gukuramo uburyo bwanduye. Muri icyo gihe, inzira itemba iroroshye, kandi umwanya wimvura igwa nayo ni nto, bityo inguni ya stroke valve ifite imikorere myiza yo guhagarika.
12 、 Ni mu buhe buryo imyanya ya valve ikeneye gukoreshwa?
（1) Mugihe cyo guterana hejuru no guhagarara neza. Kurugero, ubushyuhe bwo hejuru hamwe nubushyuhe buke bwo kugenzura valve cyangwa kugenzura valve hamwe nogupakira byoroshye;
(2) Inzira gahoro ikeneye kunoza umuvuduko wibisubizo bya valve igenzura. Kurugero, ubushyuhe, urwego rwamazi, isesengura nibindi bipimo bya sisitemu yo kugenzura.
(3) Birakenewe kunoza imbaraga zisohoka nimbaraga zo gukata. Kurugero, icyicaro kimwe cyicara hamwe na DN ≥ 25 hamwe nintebe yintebe ebyiri hamwe na DN> 100. Iyo umuvuduko ugabanutse kumpande zombi za valve △ P ＞ 1MPa cyangwa igitutu cyinjira P1 ＞ 10MPa.
